    Hy!

    I have a RC oscillator circuit with two integrators and one inverter. I do not understand how in the output can be sinus signal, when the circuit input has a DC signal. Why that circuit begins generate a sinus signal? What is here different than the Wien`i bridge RC generator?

    The other question is understanding with that line:
    Differentiating a square wave results in narrow pulses coinciding with the input transitions when the RC time constant is much smaller than the input pulse width.

    English is not my mother-tongue so I have a little problem to understand with that line.

    Can you post a picture of the circuit? The one in the OP is not working.
